Genesis Genesis 24:29-67
Bethuel and Laban speak the Akedah blessing back over Rebekah without knowing what they echo. Isaac brings her into Sarah's tent and loves her in the canon's first husband-loves-wife, and is comforted by a verb that runs forward into Isaiah's promise and the Paraclete.
Genesis 18:1-15
Yahweh comes to the door of Abraham's tent at midday and eats a meal of fine flour cakes and curds under a tree. The Hebrew names the visitor singular; the eyes see three men; the speaker is Yahweh; two leave for Sodom as angels. Sarah laughs inside the tent and the divine voice draws the laugh into the open. The vocabulary of her cakes is the vocabulary of the altar that does not yet exist; the formula of her birth-promise is the formula Elisha will speak to the Shunammite; her inner question about pleasure (ednah) is preserved by the Hebrew and erased by the Greek. At Mamre God comes to a domestic table and names the time of Isaac's life.
